1 Claim.

Thepresent invention relates to closed paper containers adapted to receive small quantities of goods which are liquid or apt to become liquid, i such as oysters, ice cream,or the like.

Heretofore, containers of this general character have been produced from two-plytubular stock made by spirally windingtwo narrow strips upon a mandrel.

inner layer. The tube thus formed is cut up in ,lengthsequalto the height of the side walls of the cover and body of the containerand a disc of cardboard is crimped in one end of each to close that end and form the top oithe cover and bottom of the body. In some cases either the edge'oi the body orthe cover is turned in topresent a rounded edge to facilitate putting the cover upon thebody.

Because such containers are made lrom twoply spirally wound sheet paper, there has been very little difliculty experienced in leakage from the container because the sidewalls oi the cover do not have any substantial tendency to warp Such containers, however, are ,ex--.

grocers or marketmen for packaging oysters or the like, the price of the foodstuff must be in,-

1 Thus, the cost of thisexpensive container becomes a burden upon the consumer or the loodstufl'.

It is an object of the present invention to provide a closed paper container adapted to receive liquid foodstuil'sand which can be produced a verylow cost and will not leak. It is another object of the invention to pro- 1 vide atwo-piececlosed container having a onepiece body and a one-piece cover constructed so that it will not leak when filled with liquid foodstuffs, such as oysters, ice cream and the like.

In accordance with more specific aspects of the invention, the body of the container of the inven-- tion is made from pulp as a, single continuous There has been available upon the market in the pasta cup-like receptacle made from pulp piece.

as a single continuous piece with a slightly tareceptacle bydrawing the outwardly extending rimflange downward ,to provide a permanent rim flange extending outward and downward in spaced relation to the sidewall of the body. The cover for the container of the invention may be made from a paper disc, such as pulp or card- 1 The strips are superimposed and ce-. wmented together and are arranged so that the seam of the outer layer overlaps the seam of the board. The disc first is drawn to cup shape with a cylindrical side wall. The open end of the cup then is turned in to provide a side wall of double thickness which prevents it from springing outward when wetted and causing leakage when the container is filled with liquid ioodstufl.

The invention will be more clearly understood from the following descriptionin conjunction with the accompanying drawing: in which,

The body 01' the container may be formed from i a one-piece receptacle I0 (Fig. 1) made from pulp i p and having a flat outwardly extending rim flange II at its open end. In accordance with the invention the flange oi the container III is permanently drawn down as indicated at I! in Fig.

The body of the container of the invention may be made from such a The cover for the container may be formed t from a single piece of cardboard in the form of a disc (not shown) which is drawn to form a cup having a flat surface I! anda cylindrical side wall I 5. The free edge of the cylindrical side wall l5 thenis turned; in as indicated at It in Fig. 4

Prelerably, the inner diameter of the cover is less than the normal outside diameter ofthe body l3 at the curved portion ll connecting the body I3 01 the container with the flange 12. Then, as the cover is placed upon the container the curved portion 11 will becontracted andtorce the flange 12 inwardly and inasmuch as the tendency of the curved portion l1 and the flange l2 isto assume their original normal positions, the flange I2 will be caused to hug tightly against the inner surface of the cylindrical wall of the cover.

If the cylindrical side wall of the cover had onlya single thickness of cardboard it would tend to spring outwardly when wet by liquid within the comcover placed upon a side wall of double thickness.

container. This difliculty is eliminated by turning in the side wall of the cover at I6 to provide Thus, as constructed in accordance with the invention the portion [6 of the side wall has a normal tendency to swing inward when wet and thus fit even more tightly against the flange I2.

I claim:

A two-piece closed paper container including a one-piece single ply body having a bottom, an annular open top and an upwardly diverging side extending from the bottom, saidside terminating in a curved portion extending outwardly and downwardly and providing a peripheral flange terminating in a free edge in spaced relation with 15 engagement of the side wall of the cover with the outer surface of the resilient flange.
